I don’t think the scraping party cares about the license, if the JavaScript code is linked online they’ll just take it. Source: see the art industry

I think AI has come as the industry was somewhat maturing and most frameworks/software had previous incarnations that mostly did the same thing or could be done adhoc anyway. The need for libraries as the models get better probably declines as well.

Not all open source but a lot of it is fundamentally for humans to consume. If AI can, at its extreme (still remains to be seen), just magic up the software then the value of libraries and a lot of open source software will decline. In some ways its a fundamentally different paradigm of computing, and we don't yet understand what that looks like.

As AI gets better OSS contributes to it; but in its source code feeding the training data not as a direct framework dependency. If the LLM's continue to get better I can see the whole concept of frameworks being less and less necessary.

They already pay people to generate training data.
